Figure 5. Rarefaction curves for the species richness of invertebrates of a grassland soil<br />

assemblage at three dates (winter experiment): A = pre-treatment; B = 20 days after<br />

treatment and C = 40 days after treatment. Continuous lines above and below Beauveria<br />

bassiana and lambda-cyhalothrin curves are 95% confi<strong>de</strong>nce limits calculated over 1000<br />

iterations (Gotelli and Colwell, 2001).<br />
